Your Path to Success: How to Pass the Oracle 1z0-822 Oracle Solaris 11 Advanced System Administration Exam

NCPs define a set of data links and IP interfaces as Network Configuration Units (NCUs).

Example:

root@solaris:~# netadm list

TYPE PROFILE STATE

ncp acme.corp.ncp online

ncu:phys net0 online

ncu:ip net0 online

ncp Automatic disabled

loc acme.corp.loc online

loc Automatic offline

loc NoNet offline

loc User disableda

The zfs get command supports the -H and -o options, which are designed for scripting. You can use the -H option to omit header information and to replace white space with the Tab character. Uniform white space allows for easily parseable data. You can use the -o option to customize the output in the following ways:

* The literal name can be used with a comma-separated list of properties as defined in the Introducing ZFS Properties section.

* A comma-separated list of literal fields, name, value, property, and source, to be output followed by a space and an argument, which is a comma-separated list of properties.

The following example shows how to retrieve a single value by using the -H and -o options of zfs get:

# zfs get -H -o value compression tank/home

on

Example. Displaying Administratively Customized Properties (here only admin layer is displayed with –l)

The following command uses SMF layers to display administratively customized properties.

example% svcprop -p config -l admin svc:/network/dns/client

(A) config/domain astring admin my.domain.com

(D) config/nameserver net_address admin 10.22.33.44 10.44.33.11

Note:

* config/nameserver refers to the Solaris DNS server.

/ The nameserver keyword specifies DNS servers to query using IP address.

Example:

The /etc/resolv.conf file contains configuration directives for the DNS resolver. The following resolv.conf example shows two name servers and three search suffixes:

domain nj.bigcorporation.com

nameserver 192.168.10.11

nameserver 192.168.20.88

* The svcprop utility prints values of properties in the service configuration repository. Properties are selected by -p options and the operands

A: Oracle Solaris Image Types include:

x86 or SPARC ISO Image for Automated Installations – The Oracle Solaris release includes the automated installer tool. The automated installer (AI) is used to automate the installation of the Oracle Solaris OS on one or more SPARC and x86 systems over a network.

D:

* You can also create custom scripts to modify your installation image. Then, you can add checkpoints to the manifest file to run these custom scripts.

* You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing. Checkpointing is optional. Default checkpoints are specified in each manifest file.

Incorrect:

Not B: Only for x86, not for SPARC-

Oracle Solaris x86 LiveCD – You can create an x86 ISO image that is comparable to the LiveCD image that's distributed as an Oracle Solaris release. You can also modify the content of this ISO image by adding or removing packages. You can revise the default settings for the resulting booted environment to create a custom ISO image or USB image.

Note: The distribution constructor creates images based on settings specified in XML files, called manifest files. The manifest files contain specifications for the contents and parameters for the ISO images that you create using the distribution constructor. The distribution-constructor package provides sample manifests that can be used to create a custom x86 Live Media ISO, an x86 or SPARC Automated Install ISO image, or an x86 or SPARC text installation ISO image.

The elements in each manifest file provide preset, default values that will create the type of ISO image you need. You can manually edit these preset elements in a manifest file to customize the resulting image. In addition, you can create custom scripts to further modify your image. Then, reference the new scripts in the manifest file.

vmstat reports virtual memory statistics regarding kernel thread, virtual memory, disk, trap, and CPU activity.

zpool detach pool device

Detaches device from a mirror. The operation is refused if there

are no other valid replicas of the data.

Create the etherstub.

global# dladm create-etherstub etherstub

Create a VNIC over the etherstub.

global# dladm create-vnic -l etherstub vnic

Note: Etherstubs / Virtual Switches

The Etherstub is craeated as a dummy device to connect the various virtual NICs. User can imagine etherstub as a Virtual Switch to help visualize the virtual network as a replacement for a physical network where each physical switch is replaced by a virtual switch.

The following list provides a brief description of each default checkpoint in the order the checkpoints are executed in most manifests.

transfer-ips-install – At this checkpoint, the distribution constructor contacts the IPS publishers and adds to the image the packages that are listed in the software_data element of the manifest.

set-ips-attributes – At this checkpoint, the constructor sets the publisher to be used by the installed system. The values set by this checkpoint are not relevant if you are building an automated installation image.

pre-pkg-img-mod – At this checkpoint, the constructor imports into the image the SMF service files that were specified in the configuration element of the manifest. Also, the constructor modifies some files to optimize the image.

* Example 1:

* man zonestat   -q         Quiet mode. Only print summary reports (requires the  -R         option). All interval reports are omitted.     -r resource[,resource]         Specify resource types on which to report. The available         resources  are: physical-memory, virtual-memory, locked-         memory,  processor-set,  processes,  lwps,   shm-memory,         shm-ids, sem-ids, msg-ids, lofi, and network.         summary         A summary of cpu, physical-memory,  vir-                         tual memory, and network usage.

* Example 2 :

The following command monitors silently at a 10 second interval for 24 hours, producing a total and high report every 1 hour:

# zonestat -q -R total,high 10s 24h 1h
